CVE-2026-9953
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOut of bounds read in ANGLE in Google Chrome prior to 148.0.7778.216 allowed a remote attacker to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High)
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn out-of-bounds read vulnerability exists in ANGLE (a graphics abstraction layer used by Chrome for WebGL) that allows a remote attacker to read memory beyond allocated buffers via a crafted HTML page, potentially exposing sensitive process memory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Chrome versionOpen Chrome, go to Settings > About Chrome, or navigate to chrome://settings/help, or run 'google-chrome --version' in terminalAffected if The displayed version is below 148.0.7778.216 (or 148.0.7778.215 for the secondary range)
-
Confirm Chrome is the primary browserDetermine if Google Chrome is actively used in the environment; check installed browsers or check default browser associationsAffected if Chrome is installed and used as a primary browser while version is below the fixed release
-
Verify ANGLE graphics library availabilityThe ANGLE library is used by WebGL; open chrome://gpu and look for 'ANGLE' under Graphics Feature Status, or test if any site uses WebGLAffected if WebGL is enabled and ANGLE is in use (this is the default state for most Chrome installations)
You are affected if Google Chrome is installed with a version lower than 148.0.7778.216 and WebGL/ANGLE functionality is available in the browser.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
